Description

Technical Field

[0001] This application relates to the technical field of hose manufacturing, and in particular to a high-efficiency automatic long-length hose manufacturing machine. Background Technology

[0002] Long-length tube making machines are specialized devices for producing metal hoses made of high-carbon steel wire, low-carbon steel wire, stainless steel wire, galvanized steel wire, and shaped steel wire. They are commonly used to produce bare tubes or metal hoses with PE polyethylene inner linings, such as spring tubes, pitch tubes, round wire tubes, shaped steel wire tubes, and double wire tubes, with diameters ranging from 4mm to 16mm. In addition, they can also be used to produce laser tubes and colored tubes. These hoses are suitable for various automotive and motorcycle assemblies, including front and rear brake cables, throttle cables, and clutch cables. They are also suitable for bicycle gearshift hoses, control hoses for various special vehicles, control cables for various machinery, and transmission flexible shaft cables and locking cables.

[0003] In existing technology, a thin, flat steel wire rope is wrapped tightly around an inner liner tube by a rotating device. Regarding the aforementioned technology, the inventors believe that due to factors such as the unwinding speed, the wire rope may not be taut and tightly wound around the inner liner tube. Furthermore, due to insufficient friction between the rotating device and the thin, flat steel wire rope, slippage may occur during the wrapping process. When these situations occur, the device needs to be stopped and manually adjusted, leading to reduced efficiency. Utility Model Content

[0004] In order to improve the working efficiency of long-length tube making machines, this application provides a high-efficiency automatic long-length tube making machine.

[0005] The high-efficiency automatic long-length tube making machine provided in this application adopts the following technical solution: A high-efficiency automatic long-length tube making machine includes a tube making machine body, a wrapping cylinder, and a wire unwinding roller. The tube making machine is equipped with a mounting box, in which the wrapping cylinder and the wire unwinding roller are coaxially arranged. One end of the wrapping cylinder is closed, and a discharge hole is opened at the center point of the closed end of the wrapping cylinder. A tension roller and a compression feeding roller are rotatably arranged at the end of the wrapping cylinder near the wire unwinding roller. There are two compression feeding rollers. A first adjusting groove is opened on the wrapping cylinder, and an adjusting block is slidably arranged in the first adjusting groove. The adjusting block is rotatably connected to the tension roller. A driving component for driving the adjusting block to slide is provided on the wrapping cylinder. The length direction of the first adjusting groove is perpendicular to the line connecting the two compression feeding rollers.

[0006] By adopting the above technical solution, one end of the inner liner tube extends from the discharge hole, and the flat steel wire rope passes sequentially between the tension roller and the two extrusion feeding rollers, finally winding around the inner liner tube to achieve the wrapping operation. When the wire feeding speed is too fast, the adjusting block moves in the first adjusting groove under the driving action of the drive component until the flat steel wire rope is re-tensioned, making it easier for it to be wrapped more stably around the outside of the inner liner tube. Through the cooperation of the tube making machine body, the wrapping cylinder, and the wire unwinding roller, the working efficiency of the long-length tube making machine is improved.

[0007] Optionally, the wrapping cylinder is provided with a second adjusting groove, the length direction of the second adjusting groove is perpendicular to the length direction of the first adjusting groove, two sliding blocks are slidably arranged in the second adjusting groove, the two sliding blocks correspond one-to-one with the two extrusion feeding rollers and are rotatably connected, a bidirectional screw is rotatably arranged in the wrapping cylinder along the length direction of the second adjusting groove, the two ends of the bidirectional screw are provided with threaded sections with opposite directions of rotation, one end of the sliding block extends into the wrapping cylinder, the two sliding blocks correspond one-to-one with the two threaded sections of the bidirectional screw and are threadedly connected.

[0008] By adopting the above technical solution, the distance between the two extrusion feeding rollers needs to be adjusted to accommodate flat steel wire ropes of different thicknesses and different feeding requirements. Twisting the bidirectional screw causes the two sliding blocks to move closer to or further apart under the drive of the bidirectional screw and the limiting action of the second adjusting groove, thus achieving the adjustment of the distance between the extrusion feeding rollers and expanding the applicability of the device.

[0009] Optionally, the extrusion feed roller is provided with an installation ring groove along its peripheral wall, and an anti-slip washer is embedded in the installation ring groove. The outer peripheral wall of the anti-slip washer is flush with the peripheral wall of the extrusion feed roller.

[0010] By adopting the above technical solution, the anti-slip washer increases the friction between the flat steel wire rope and the extrusion feeding roller, reducing the possibility of the flat steel wire rope slipping during the wrapping process.

[0011] Optionally, a cutting assembly is provided between the wrapping cylinder and the wire unwinding roller. The cutting assembly includes a support frame, a support plate, a cutting blade, and a lifting plate. The support frame is disposed in the mounting box and located between the wrapping cylinder and the wire unwinding roller. The support plate is vertically disposed on the support frame, and a support groove is provided on the top edge of the support plate. The lifting plate is horizontally disposed in the mounting box. The cutting blade is vertically disposed on the bottom surface of the lifting plate, and a cutting groove is provided on the bottom edge of the cutting blade. A driving component for driving the lifting plate to move vertically is provided in the mounting box. One side of the cutting blade and one side of the support plate are fitted together in the vertical direction.

[0012] By adopting the above technical solution, when the inner lining tube is first wrapped, the inner lining tube to be processed is placed in the support groove of the support plate. The lifting plate descends under the driving action of the drive component, and the cutting blade cuts off the end of the inner lining tube flat, realizing the automatic cutting of the inner lining tube and improving the processing efficiency of the inner lining tube.

[0013] Optionally, the support frame is provided with a clamping V-shaped plate, the opening of the clamping V-shaped plate is arranged facing upward, and the bottom end of the clamping V-shaped plate is arranged in a horizontal direction corresponding to the bottom end of the support groove and the discharge hole.

[0014] By adopting the above technical solution, when cutting the inner lining tube, the inner lining tube is placed in the groove of the clamping V-shaped plate, and the clamping V-shaped plate supports the inner lining tube, which further reduces the possibility of the inner lining tube coming out of the support groove during the cutting process.

[0015] Optionally, a pressing plate is provided below the lifting plate, and a relief groove corresponding to the shape of the pressing plate is provided on the clamping V-shaped plate. The relief groove is provided in the vertical direction corresponding to the pressing plate. An elastic element is provided between the pressing plate and the lifting plate. In the natural state, the height of the pressing plate is lower than the height of the cutting blade.

[0016] By adopting the above technical solution, when the lifting plate descends with the driving component, the pressing plate passes through the relief groove on the clamping V-shaped plate, and finally the pressing plate presses the inner liner tube placed inside the clamping V-shaped plate, further reducing the possibility of the inner liner tube shaking during the cutting process.

[0017] Optionally, a limiting annular groove is provided circumferentially on the peripheral wall of the tensioning roller.

[0018] By adopting the above technical solution, during the wrapping process, the flat steel wire rope is embedded in the limiting ring groove of the tensioning roller, and the setting of the limiting ring groove reduces the possibility of the flat steel wire rope separating from the tensioning roller during the tensioning process.

[0019] Optionally, a pressing plate is provided on the wrapping cylinder, and one side of the pressing plate extends into the limiting annular groove of the tensioning roller.

[0020] By adopting the above technical solution, the pressing plate presses the flat steel wire rope in the limiting ring groove, so that its wider side can be stably attached to the inner wall of the limiting ring groove, which facilitates the subsequent stable winding of the flat steel wire rope on the inner liner tube.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the tube making machine body, the wrapping cylinder and the wire unwinding roller, the working efficiency of the long tube making machine is improved. 2. The cutting component enables automatic cutting of the inner lining tube, which facilitates improved processing efficiency of the inner lining tube; 3. The pressing plate presses down on the flat steel wire rope in the limiting ring groove, so that its wider side can be stably attached to the inner wall of the limiting ring groove, which facilitates the subsequent stable winding of the flat steel wire rope on the inner liner tube.

[0033] Reference Figure 2-4 During processing, the inner liner tube 6 discharges through the discharge hole 93. The flat steel wire rope 8 on the wire unwinding roller 4 passes sequentially through the guide hole 101 on the guide plate 10, the tension roller 13, and the two extrusion feeding rollers 11, and is finally wound onto the inner liner tube 6. To accommodate flat steel wire ropes 8 of different thicknesses or processing requirements, the double-acting screw 16 is turned. Under the limiting action of the second adjusting groove 92 and the guiding action of the double-acting screw 16, the two sliding blocks 15 move towards or away from each other, thus adjusting the spacing of the extrusion feeding rollers 11 and expanding the applicability of the device. When the flat steel wire becomes loose, the tensioning cylinder 19 is activated, driving the tensioning roller 13 to move on the winding cylinder 9, ensuring that the flat steel wire rope 8 remains taut and stably wound.

[0034] Reference Figure 2 and Figure 4The limiting groove 131 reduces the possibility of the flat steel wire rope 8 detaching from the tension roller 13 during the wrapping process. The clamping plate 21 presses the wider side of the flat steel wire rope 8 into the limiting groove 131, facilitating the stable wrapping of the flat steel wire rope 8 onto the inner liner tube 6. The anti-slip washer 14 increases the friction between the flat steel wire rope 8 and the extrusion feed roller 11, reducing the possibility of slippage during the wrapping process.

[0035] Reference Figure 2 Before processing begins, the lifting plate 22 descends under the drive of the lifting cylinder 23, and the inner liner tube 6 is placed in the clamping V-shaped plate 52 and the support groove 571. The pressing plate 53 passes through the relief groove 521 and presses the inner liner tube 6 tightly, reducing the possibility of the inner liner tube 6 shaking during the cutting process. The support plate 57 and the cutting blade 58 simultaneously cut the inner liner tube 6, realizing automatic cutting of the inner liner tube 6 and helping to improve the processing efficiency of the device.

[0036] The implementation principle of a high-efficiency automatic long-length tube making machine in this embodiment is as follows: During processing, the inner liner tube 6 is discharged through the discharge hole 93. The flat steel wire rope 8 on the wire unwinding roller 4 passes sequentially through the guide hole 101 on the guide plate 10, the tension roller 13, and two extrusion feeding rollers 11, and is finally wound onto the inner liner tube 6. To adjust the spacing of the extrusion feeding rollers 11, the bidirectional screw 16 is turned to accommodate flat steel wire ropes 8 of different thicknesses or processing requirements, thus expanding the applicability of the device.

[0037] Before processing begins, the inner liner tube 6 is placed in the clamping V-shaped plate 52 and the support groove 571. The pressing plate 53 presses the inner liner tube 6 tightly, reducing the possibility of the inner liner tube 6 shaking during the cutting process. The support plate 57 and the cutting blade 58 simultaneously cut the inner liner tube 6, realizing automatic cutting of the inner liner tube 6.
